how do the mouse get onto the can? do they have to make a flying leap or is the can closer to the edge. It seems to me that the plate provides an easy bridge to the bait (granted some coming from the other side may have to jump to it, if the plate hasn't flipped). if it is easiest for the mice, we could probably get more, maybe.
i think, imho, that OP should just keep trying with the plate. come real cold, you'll surely get some. course, no haarm trying diff. models. I'm makin me one a those!!
thanks!
